Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting and grinding, in particular to a sandblasting device for stainless steel plates. Background Art

[0002] In modern industrial production, the sandblasting and grinding of stainless steel plates is an important surface treatment process. It can not only beautify the surface of the plates and improve the visual effect of the products, but also effectively remove burrs, dirt and oxide layers on the surface of the plates, laying a good foundation for subsequent processing or direct use.

[0003] The traditional sandblasting device for stainless steel plates sprays sand grains onto the surface of the plates at high speed through a preset sandblasting gun or sandblasting head to achieve fine grinding of one side of the plates. However, when dealing with stainless steel plates that need to be sandblasted on both sides, the operator has to manually take out the plate from the device, turn it over after completing the sandblasting and grinding of one side, and then put it back into the device for sandblasting the other side. This process is not only cumbersome and time-consuming, but also greatly increases the labor intensity of the operator. At the same time, there is also a risk of plate damage during multiple handling and turning processes. Therefore, a sandblasting device for stainless steel plates is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings in the prior art that when dealing with stainless steel plates that need to be sandblasted on both sides, the operator has to manually take out the plate from the device, turn it over after completing the sandblasting and grinding of one side, and then put it back into the device for sandblasting the other side. This process is not only cumbersome and time-consuming, but also greatly increases the labor intensity of the operator. At the same time, there is also a risk of plate damage during multiple handling and turning processes, and a sandblasting device for stainless steel plates is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] In a possible design, the turning-over mechanism includes an L-shaped plate. Incomplete gears are provided on both sides of the L-shaped plate. On the side of the two L-shaped plates close to each other, a same first rotating shaft is fixedly connected. The first rotating shaft fixedly penetrates through the two L-shaped plates and the four incomplete gears. The first rotating shaft is rotatably connected between the first column and the third column, and the first rotating shaft rotatably penetrates through the second column.

[0009] In a possible design, the transmission mechanism includes a motor, a second rotating shaft, three third rotating shafts, two fourth rotating shafts, and a fifth rotating shaft. The motor is fixedly connected to the bottom inner wall of the installation groove. The output shaft of the motor penetrates through one side of the installation groove. One end of the output shaft of the motor located in the first accommodation groove is fixedly connected with a first gear. The second rotating shaft is rotatably connected between the first column and the third column. The second rotating shaft respectively penetrates through the two first accommodation grooves and the second accommodation groove rotatably. Three first worms are sleeved on the circumferential outer wall of the second rotating shaft. The three first worms are respectively located in the two first accommodation grooves and the second accommodation groove. A second gear is fixedly connected to the circumferential outer wall of the second rotating shaft located in the first accommodation groove with the first gear. The second gear meshes with the first gear. The three third rotating shafts are respectively rotatably connected to the inner walls on both sides of the two first accommodation grooves and the second accommodation groove. One end of the circumferential outer wall of the third rotating shaft is fixedly connected with a first worm gear. The first worm gear meshes with the corresponding first worm. A second worm is sleeved on the other end of the circumferential outer wall of the third rotating shaft. The two fourth rotating shafts are respectively rotatably connected to the first accommodation grooves opened inside the first column and the third column. One end of each of the two fourth rotating shafts rotatably penetrates through one side inner wall of the corresponding first accommodation groove. The fifth rotating shaft is rotatably connected to the inner walls on both sides of the second accommodation groove.

The four gears respectively mesh with the corresponding incomplete gears.

[0010] In a possible design, the two fourth rotating shafts and the fifth rotating shaft are located on the same axis. The first rotating shaft, the second rotating shaft, the two fourth rotating shafts, and the fifth rotating shaft are arranged parallel to each other. The three third rotating shafts are arranged perpendicular to the second rotating shaft.

[0011] In a possible design, the reset mechanism includes a slider. The slider is slidably connected to the inner wall of the sliding groove. A resisting block is fixedly connected to one side of the slider. The resisting block slidably penetrates through the sliding groove. The same reset spring is fixedly connected between the other side of the slider and one side inner wall of the sliding groove.

[0012] In a possible design, the top of the resisting block contacts the L-shaped plate. A first inclined surface is opened on the top of the resisting block. A second inclined surface is opened on the bottom of the resisting block. The length of the second inclined surface is greater than that of the first inclined surface.

[0013] In this application, when sandblasting treatment is required for stainless steel plates, the equipment is first started, and then the steel plate to be sandblasted is placed on the conveyor belt of the belt conveyor. Then, the steel plate to be sandblasted is transported into the sandblaster by the belt conveyor for sandblasting treatment. After one side of the steel plate to be sandblasted is sandblasted, the belt conveyor drives the steel plate to be sandblasted to continue moving. When the steel plate to be sandblasted contacts the L-shaped plate, the belt conveyor continues to drive the steel plate to be sandblasted to move. Then, the steel plate to be sandblasted pushes the L-shaped plate to rotate along the first rotating shaft. At the same time, the first rotating shaft drives the incomplete gear to rotate, so that the incomplete gear meshes with the third gear. Then, the motor drives the third gear to rotate through the worm and worm gear transmission, and then drives the incomplete gear through meshing, and then drives the L-shaped plate to flip along the first rotating shaft, so as to realize the flipping of the steel plate to be sandblasted. Then, after the steel plate to be sandblasted is transported away by the belt conveyor, the L-shaped plate continues to flip and contacts the abutting block, and the second inclined surface opened at the bottom of the abutting block is used to push the reset mechanism to move inwards. When the bottom of the L-shaped plate contacts the first inclined surface opened at the top of the abutting block, the incomplete gear disengages from the third gear due to the missing teeth, and the L-shaped plate is reset under the elastic force of the reset spring, and then the flipping of the next steel plate to be sandblasted can be carried out.

[0014] In this utility model, for the sandblasting device for stainless steel plates, through the setting of the flipping mechanism, by using the cooperation of the L-shaped plate and the incomplete gear and precisely controlling through the transmission mechanism, the automatic flipping of the stainless steel plate during the sandblasting process is realized. This design completely changes the cumbersome process of manually flipping the plate in the traditional sandblasting device. Since the automatic flipping of the plate is realized, this device can continuously sandblast both sides of the plate without interruption and waiting, thus significantly shortening the overall sandblasting operation time, improving the production efficiency and production capacity. At the same time, the operator no longer needs to carry out the repetitive and heavy plate flipping work, greatly reducing their physical labor burden, and also avoiding the damage to the plate caused by improper operation or uneven force during manual flipping, ensuring the surface quality and integrity of the plate.

[0015] In this utility model, for the sandblasting device for stainless steel plates, through the setting of the reset mechanism, the cooperation of the slider, the abutting block and the reset spring can be used to automatically reset the L-shaped plate to the initial position after the flipping action is completed, preparing for the next flipping action. The inclined surface design optimizes the reset process and improves the reset accuracy and efficiency.

[0016] In the present utility model, automatic flipping of stainless steel plates during the sandblasting process can be achieved. This design completely changes the cumbersome process of manually flipping plates in traditional sandblasting devices. Since automatic flipping of the plates is realized, this device can continuously perform sandblasting on both sides of the plates without interruption, thus significantly shortening the overall sandblasting operation time, improving production efficiency and production capacity. At the same time, operators no longer need to perform repetitive and heavy plate flipping work, greatly reducing their physical labor burden, and also avoiding plate damage caused by improper operation or uneven force during manual flipping, ensuring the surface quality and integrity of the plates. Moreover, with the cooperation of the slider, abutting block, and return spring, the L-shaped plate can be automatically reset to its initial position after the flipping action is completed, preparing for the next flipping action. The inclined plane design optimizes the reset process, improving the reset accuracy and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
